Meeting the family of your Intended, not just Mommy and Daddy, but the whole genetic interplay, is better than gazing into a crystal ball.
Looking at them, not only the shapes and styles but the interactions between them, you can see ‘the future’; that is Your Future.
You can see where your intended will be in twenty/thirty years.
Not just physically, but emotionally, intellectually; in short, it is likely what s/he will become is portrayed by those relatives in front of you.
When you meet them you can see not only their life styles, but how they interact, what matters to them, what doesn’t.If you don’t like what you see, get out now.
Don’t think your intended is an aberration from his gene pool.
